Since then I switched to Mint Cinneamon, where suspend mode seems to work properly, even though battery life is still poor. Then in Mint I installed gnome and logged into it, there the problem with suspend popped up again. So the problem is definitely in gnome (most probably in gnome-power-manager).

Hardware model: ASUSTeK COMPUTER INC. VivoBook_ASUSLaptop X513EAN_K513EA Memory:16,0 GiB Processor: 11th Gen Intel® Core™ i7-1165G7 × 8 Graphics: Mesa Intel® Xe Graphics (TGL GT2) Disk capacity: 1,0 TB (SSD) OS Name: Ubuntu 22.10 OS Type: 64-bit Gnome version 43.1 Windowing system: Wayland 2- Package gnome-power-manager 43.0-1 3-Expectd that when I set power mode to Power Saver that it stays there, and when I suspend or put to sleep the laptop, battery level drops very slowly 4- If I manually set the power-saving mode, it reverts to balanced within less than a minute. This is reproducible every time and does not dependent on whether there's a power supply or on battery. while using the laptop with simple office work (no video, no audio), it drains the battery in less than 5 hours while the vendor claims 7 hours of heavy duty. even in sleep or suspend mode it drains the battery quickly. Almost half of normal consumption while used. At startup I can see error messages related to ACPI (see the screen shot). No idea if this can explain. the laptop is on dual boot Windows 11/Ubuntu 22.10 latest updates and I do not notice the same problem under windows 11.
